\begin{matrix} r = & 8 m \end{matrix}

$\begin{array}{r} r = & 8 m \end{array}$

Step 1

The area of a circle is equal to Pi

π

$π$ times the radius

r

$r$ squared.

π \cdot {(r a d i u s)}^{2}

$π \cdot {(r a d i u s)}^{2}$

Step 2

Substitute in the value of the radius

r = 8

$r = 8$ into the formula for the area of a circle. Pi

π

$π$ is approximately equal to

3.14

$3.14$ .

π \cdot 8^{2}

$π \cdot 8^{2}$

Step 3

Raise

8

$8$ to the power of

2

$2$ .

π \cdot 64

$π \cdot 64$

Step 4

Move

64

$64$ to the left of

π

$π$ .

64 π m^{2}

$64 π m^{2}$
